Why is human blood type an example of multiple alleles? codominance?

It is because when alleles show a co-dominant relationship , neither allele is dominant and both are expressed in the phenotype of the heterozygote. The human ABO blood groups provide a good example of codominace. The ABO system is due to a gene that codes for molecules on the surface of red blood cells

pH value of acids are betwee 0 and 7 while in bases the pH value os between 7 and 14

acid is called a proton donor while a base is called a proton acceptor

base can accept a proton while an acid can accept an electron pair

acids are substance that give off hydrogen ions to form hydronium (H30) ions when dissolved in water while bases are substances that contain hydroxide (OH) ions when in water

The transfer of genes from donor to recipient in microorganisms, where the recipient strain shows a change in genetic makeup at the end, is referred to as genetic recombination.

<h3>What is genetic recombination?</h3>

Genetic recombination is the formation of genetic combinations in offspring that are not present in the parents.

Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles. This recombination process creates genetic diversity at the level of genes that reflects differences in the DNA sequences of different organisms.

In eukaryotic cells, which are cells with a nucleus and organelles, recombination typically occurs during the metaphase stage of meiosis.

The aim of genetic recombination is to produce offsprings with combinations of traits that differ from those found in either parent.
